Audio Transducer Study.
Abstract
This document covers the technical detail in the work performed to date on the development of state-of-the-art contact microphones, electret airpath microphones, and dynamic airpath microphones, small dynamic and electret earphones, and a small lightweight loudspeaker. These transducers are to be small, lightweight, have low visibility, employ hands free operation, and not interfere with the user's senses. (Modified author abstract)
